PLIERS FOR WIRE FENCES- SPEGIFICATION forming part of Letters Patent No. 782,868, dated February 21, 1905.

Application filed March 26, 1904:. Serial No. 200,109.

To (LZZ whom it may concern.-

invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in plate-clamping pliers for wire fences.

The object of this invention is to devise pliers which are adaptable for clamping a plate of a particular pattern or design expeditiously and securely upon two crossed wires Where they cross each otheras, for instance, at the junction of a stay-forming vertical wire with each longitudinal or horizontal wire or strand of a wire fence.

My invention consists in improved pliers comprising the following: one member having a broad end jaw provided with a laterallyextending boss and a recess therein and two straightening-lugs at opposite sides, respectively, of the boss, a longitudinally-movable clamping-bar provided with a grooved end jaw and held in suitable guideways in the aforesaid and relatively stationary jaw-bearing member of the pliers, and another member constituting a lever pivoted in the first-,

mentioned jaw-bearing member of the pliers and provided with a cam-shaped end whereby the aforesaid bar is forced outwardly to exert the desired pressure upon the plate and crossed wires.

My invention consists also in the details of construction and combinations of parts hereinafter described, and pointed out in the side elevation corresponding with Fig. 2, except that in Fig. 5 portions are shown in central section and the pliers are shown operating upon two crossed fence-wires and wireconnecting plate. Fig. 6 is a side elevation showing two wires crossing each other and the wire-connecting plate.

In the drawings like letters of reference indicate corresponding parts in each figure.

Referring to the drawing, A designates one member of the pliers, and B a lever-forming member arranged longitudinally of the relatively stationary member A. The parts A and B are provided at their outer ends with handles a and t, respectively, as shown in Fig. 5. The lever B is pivoted or fulcru med a suitable distance from its inner extremity to the member A, as at b. The inner end B of the lever B is cam-shaped and extends at the inner side of the pivot Z) into the recess or slot a, formed in and extending longitudinally of the part A. The member A extends a suitable distance beyond the cam-shaped end B of the lever B and terminates in a broad-shaped end jaw A, which projects from the body portion of the member A in somewhat the form of a crook and is provided with the guide-lugs (6 and 0 arranged at the upper side and lower side,

respectively, of a boss aiwith which the jaw,

A is centrally provided. In the boss (0 is formed a laterally-extending recess 0*, having a central depression or enlargement a" to permit the giving of the requisite bend to the longitudinalor horizontal wire Z, as will hereinafter appear.

O represents the clamping-bar, which is substantially rectangular in form and has a broad end jaw 0, having the groove 0, which is arranged at a right angle to the recess a". The groove 0 is designed to receive the vertical wire or stay 8.

The bar C is suitably held in but movable endwise of the recess a, longitudinally of the member A, toward and from the jaw A. A suitably-applied spiral spring D acts to move the bar O against the cam-shaped end B of the lever B, and consequently away from the jaw A. The spring D is located in an opening O, formed in the bar C, and extends between the inner end of the bar and a pin (Z,

borne by the part A and extending laterally l and the plate receives the bends e 6, whereby through the opening 0.

By the construction hereinbefore described it will be observed that the movable jaw c and the relatively stationary jaw A face each other, that the recess a and the groove 0 are formed at a right angle to each other in the face of the jaw A and jaw 0, respectively,

and that the recess a is enlarged in depth opposite the groove 0'. It will be observed also that the face of the jaw A is recessed or cut away vertically, as at a, above and below the recess a and opposite the recess 0 in the jaw c to accommodate the reception of the vertical wire 8 and that the lugs a afford bearing to the wire and are instrumental in straightening the said wire and maintaining the wire straight above and below the place where the plate E is attached to the wire.

The plate E, employed in connecting the two wires 8 and Z together, at the junction of the said wires is substantially broad,V-shaped in cross-section before it is placed in position, and mounted on the wires, as shown in Fig. 6, wherein the vertical wire .s extends through holes E. formed in the upper and lower portions of the plate.

In the operation of the pliers the groove 0 of the movable end jaw c engages the vertical wire .5, so as to cause the said jaw to straddle the said wire, and the recess a" of the relatively stationary jaw A engages the horizontal wire l, so as to cause the last-mentioned jaw to straddle the horizontal wire. The groove (0 and its central enlargement a? have the dimensions required to accommodate the plate E, which at its upper and lower ends extends into the groove 0 in the jaw 0 during the operation of the pliers, as shown in Fig. 5. The arrangement of the parts is such, therefore, that during the operation of the pliers mutually-engaging reverse bends are formed upon the wires 8 and Z where they cross each other, as shown in Figs. 4, 5, and 6.

The plate P has, of course, a broader V- shaped form before it is clamped to the fencewires; but upon the exertion of pressure thereon by the movable jaw c the said wires and the said plate are clamped together, as shown,

the vertical wire is securely gripped. It will also be seen that the central depression a or central enlargement in depth of the recess 64* freely accommodates the bend of the horizontal wire Z, and the plate E is held in position by its engagement with the said recess preparatory to and during the operation of the pliers.

By the pliers hereinbefore described I am enabled-when the plate E is first placed in position on the crossed wires to quickly and expediently bend the plate flatter from end to end, and thereby grip the vertical wire securely, and displacement of the parts operated upon longitudinally, as well as vertically, is effectually prevented.

What I claim is- 1. In pliers of the class described, the combination, with one member having two straightening-lugs arranged a suitable distance apart and a boss formed centrally between the said lugs and provided with a laterally-extending recess, of a movable jaw having a groove arranged at a right angle to the aforesaid recess, and means for actuating the said jaw.

2. Pliers comprising two cooperating jaws, one movable toward and from the other, with the last-mentioned jaw relatively stationary and with the two jaws facing each other; a groove formed in the face of the movable jaw; a recess formed in the face of the relatively stationary jaw centrally between the ends of and arranged at a right angle to the groove in the stationary jaw and increased in depth at its central portion; means for actuating the movable jaw, and the two wire-straightening lugs formed upon the relatively stationary jaw and arranged adjacent to and a suitable distance from opposite ends respectively of the groove in the movable jaw.

In testimony whereof I sign the foregoing specification, in the presence of two witnesses, this 23d day of March, 1904, at Cleveland,

Ohio.
